ABSTRACT

Density and viscosity were determined for binary mixtures containing 1-decanol and three fragrance raw materials based on cyclohexane: cyclohexyl carboxylic acid (CCA), or cyclohexyl acetate (CA), or 2-cyclohexyl ethyl acetate (2CEA) in wide range of temperatures from 300 to 340K and atmospheric pressure. Excess molar volumes were calculated and correlated by the Redlich Kister polynomial expansions involving parameters dependent on temperature for the mixtures. The polynomial correlations describe the variation of density and viscosity with composition. The coefficient of thermal expansion, ^2 was described for all pure fragrance rawmaterials and their mixtures and related excess property has been calculated. The temperature dependence of density and viscosity for these systems can be described by an empirical second-order polynomial and by the Vogel Fulcher Tammann equation, respectively. Comparison of the results for three binary systems elucidates the influence of the substituent at the cyclohexane ring on their physical and volumetric properties.
